Please Note:
Due to the size of this tank, it ships separately and is unboxed. Expect it to arrive in good condition with some cosmetic marks from shipping and handling. This tank ships directly from the manufacturer.

To install this tank, you must remove the belly pan. You cannot do it from the top side because a steel stringer (thus the odd top shape of the tank) prevents you from getting the tank out. When you do remove the belly pan you will see a piece of plywood that supports the tank. That plywood is supported by an angle iron frame. The plywood slides in place from one end of that frame and then is secured with a removable piece of angle iron. You wanted to remove the belly pan anyway, right?
